Never for a second did I think that Gemina could possibly be as good as Illuminae but I was proven wrong. This is another fantastic novel from Kaufman and Kristoff, I just can't get enough of this series.

Although there are still links to Illuminae and cameos from some of our favourite original characters, Gemina is very much a whole new story. I really liked the new characters. I thought that Hanna, Nik and Ella were all very different to one another and I was somehow able to identify with all of them, something which is essential for me when reading a book. Hanna is sassy and strong-willed, Nik is a softie deep down and Ella is actually pretty badass. There were some really funny moments between these three and I really felt quite attached to them.

The plot was exciting but maybe not quite as thrilling as Illuminae. Whereas the idea of the Phobos virus was completely terrifying, I wasn't so terrified by the alien-like creatures in Gemina. I mean, they weren't exactly fluffy puppies but I didn't really feel that they featured enough to truly be scary to me as a reader. Saying that, plenty happens and this book is still rammed full of delicious twists and turns that kept me wanting more.

I again loved the formatting of the book. These books are so unique to me and I honestly will never get bored of them. I would have really loved to see more of the doodles from Hanna's journal that we saw at the beginning. There were a lot of surveillance reports in this which made it feel wordier than Illuminae, but this didn't affect me enjoyment at all.

The ending of this book was so abrupt that I found myself searching for more pages. I'm not sure how I'm going to wait for the next instalment!
